EMC6W201-AEZG-TR

Thermal Management Overview

The EMC6W201-AEZG-TR is a board-mount environmental monitoring device and piecewise linear fan controller designed for multi-processor systems. It operates on a 3.3V supply with 5V tolerant input buffers and features an SMBus 2.0 compliant interface. The device monitors up to six voltages, including +1.5V, +2.5V, +5V, VCC, and two VCCP rails. It supports five remote thermal diodes plus one internal ambient sensor with +/- 3°C accuracy. Fan speed control utilizes three PWM outputs adjustable from 15kHz to 30kHz, while four tachometer inputs monitor fan speeds.

Thermal Management Feature Summary

• Provides automatic fan control using piecewise linear algorithms based on temperature and ProcHot signals.
• Monitors multiple system parameters including six voltage rails and five external thermal sensors alongside internal ambient temperature.
• Features acoustic enhancement modes and ramp rate control to minimize noise during fan speed adjustments.

Thermal Management Applications

• Multi-processor system hardware monitoring
• Automatic DC fan speed control in server environments
• System thermal management with ACPI compliance

Thermal Management Procurement Notes
